Embodiment Construction

[0021] Such as figure 1 As shown, the sensor is mainly divided into a bundled adjustable belt part (101), a strain circuit part, a breathing reminder light (102), a sensor shell (103) and a transmission wire part.

[0022] Such as figure 2 As shown, first, the sensor (202) is fixed on the abdomen of the user by using the belt, and the front and back of the sensor can be judged by the position of the breathing light. The side where the LED light is located is the front, away from the abdomen, and the other side is close to the abdomen. Further, the user adjusts the tightness of the waist belt (201) to an appropriate degree, that is, the degree to which the sensor does not hinder the user's breathing and the pressure on the sensor can change with the user's breathing process. Further, the pressure-strain circuit part converts the rhythmic volume change of the abdomen with the change of respiration into the change of the pressure on the sensor and converts the change into a vol...

Abstract

The patent of the invention designs a respiratory rhythm detection sensor for a slow breathing training blood pressure therapeutic instrument. The principle that the abdominal cavity volume changes rhythmically along with respiration of a human body is designed and utilized, the pressure change, caused by the abdominal cavity volume change, of the sensor can be converted into a rhythmic electric signal through a bridge circuit composed of an elastic element and a strain gauge, and therefore the purpose of measuring the respiratory rate is achieved.

Description

【Technical field】 [0001] The patent of the present invention relates to the field of medical devices, in particular to the design of a respiratory rate sensor used in a therapeutic instrument for hypertension. 【Background technique】 [0002] About 90% of hypertensive patients in my country die from hypertensive complications such as cerebral congestion, myocardial infarction, cerebral infarction, uremia, and renal failure. The average life expectancy of hypertensive patients is only 54.7 years, which is usually 20 years shorter than that of normal people. [0003] It can be seen from the classification of hypertension in my country that hypertension is defined as systolic blood pressure>=140mmHg and (or) systolic blood pressure>=90mmHg. The key to effective control of high blood pressure is to treat blood pressure to reach the target and keep it at the target level for a long time, and to achieve the target is if the blood pressure level is below the definition level ...
